PIPE-BOILER.

SPECIFICATION forming part of Letters Patent No. 659,645, dated October16, 1900.

Application filed October 31, 1899. Serial No. 735,412. (No model.)

To @ZZ whom t may concern:

Be it known that I, CHARLES D. OAsAD, a citizen of the United States,residing at Seattle, in the county of King and State of Washington, haveinvented certain new and useful Improvements in Pipe-Boilers, of whichthe following is a specification, reference being had therein to theaccompanying drawings.

My invention relates to certain new and useful improvements inpipe-boilers; and it consists in the novel manner of combining the partshereinafter described and pointed out in the claims.

The objects of my improvements are, first, to provide means of unitingthe several principal members of a pipe-boiler without the necessity ofusing either pipe-unions or the said pipes having oppositelycut threadsthereon; second, to permit the boiler being enlarged or decreased insize to suit varying requirements, and, third, to furnish a means of'constructing a boiler that may be readily taken apart to be packed forshipment in a small space and again assembled by any person of ordinaryintelligence.

Referring to the accompanying drawings, forming a part of thisspecification, in which similar letters refer to corresponding parts inall the views, Figure l is a side elevation of a pipe-boiler, parts ofwhich are in section to show my invention. Fig. 2 is a front elevationof the boiler with my invention applied thereto, and Fig. 3 is aperspective view of a steam-generating coil and connections.

In the drawings, A is a steam-drum.

B B are short lengths of pipes orinterfitting pipe-sections arranged inseries to form the Water-drums, and the several pieces are connectedbysteain-generating coils C C to a similar series D D, forming thesteam-separating drums, these coil-pipes C C connecting thepipe-sections in pairs, so that when the staybolts J .I are removed thepairs of sections, with their connecting-pipes, are independentlyremovable.

E E are down-dow pipes, and F F are transverse pipes making connectionbetween the aforesaid separating-drums and the steamdrum A.

The several pieces B B and D D are of peculiar shape, their ends beingground to make steam-tight joints by rounding one end b to fit intohub-shaped or bell-mouthed end b" of the adjoining piece and into thefittings P,

said pieces B and D having side 'outlets O,

screw-threaded for the reception of the steamgenerating coils C. Thetransverse connecting-pipes F and the flanged pipes G, secured tosteam-drum heads, are likewise ground fo fit into corresponding seatsinthe fittings H H. All of these detachably-seated connections are heldtogether by through stay-bolts J J, preferably hollow and drawn up tomake steam-tight joints by nuts screwed upon their ends.

What I claim as new, and desire to secure by Letters Patent, is-' y 1.In a pipe-boiler, the combination with supporting down-dow pipes, ofWater-drums and steam-separating drums, connected to and supported bythe said down-110W pipes, and each comprising a seriesof pipe-sectionshaving interfitting ends, means for securing the pipe-sections of eachdrum together, and coil-pipes connecting such pipe-sections in pairs, sothat each pair of pipe-sections with the connecting coil-pipe isindependently removable.

2. In a pipe-boiler, the combination with supporting down-flow pipes, ofWater-drums and steam-separating drums, connected to and supported bythe said down-flow tubes, and each comprising a series of pipe-sectionshaving interfitting ends, stay-bolts for securing the pipe-sections ofeach drum together, coil-pipes connected to the respective pipesections,a steam-drum, pipes connected to the steam-separating drums and to thesteamdrum by detachably-seated connections, and stay-bolts for holdingsuch detachably-seated connections together, so as to enable separationof the parts. A

In testimony whereof I affix my signature in presence of two Witnesses.

CHARLES D. CASAD.

PIERRE BARNES, ERNEST E. GILMER.
